Hello, guys I'm having a small challenge at school,
Where I need to reverse an encryption function to find the decryption function..

Im originally a javascript developer so i find it a bit hard to understand whats going on here:

Code

def GGGGotate(lol):
    bit = lol << 1
    movebit = bit & 255
    if (lol > 127):
    movebit = movebit | 1
    return (movebit)

If anyone can help me reverse this or simply understand what's going on it will be greatly appreciated.

PS: this is only a small part of the encryption function where I'm stuck it's not the full function!
